drm: inline drm_agp_destroy
Wrapping a kfree is pointless. v2: Add a comment to the kerneldoc for drm_agp_init to explain where the kfree happens as requested by David. Note that for modeset drivers agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop and drivers must call drm_agp_release on their own. Which they all seem to do properly.
